| 摘 要： | 利用华南花岗岩同位素年令数据的统计分布特征,提出了该地区花岗岩岩浆活动最频繁的时间区间和活动规模最大的峰值期;由统计分布曲线的近正态分布,提出了该区岩浆活动由弱变强再变弱的变化趋势;在空间上认为华南岩浆侵入活动中心有向南迁移的趋势,这一推断通过所进行的一维趋势分析得到了佐证。

| Abstract: | This paper utilizing the statistical distributional characteristics of the isotopic geological age data in South China, mentions the most frequent time's district and the greatest crest period of the granitic magma activity in this region. According to the near normal distribution curve, magma activity tends from weak to strong to weak again and intrusive ctive centre tends from north to south The inference is proved by one
